This fault occurs when the actuator stroke time of travel is greater than the value entered for the effective stroke time.

About this task

Note: You can add this alarm if the parent network engine is at Release 11.0 or later.
Note: Configure the Effective Stroke Time parameter during the commissioning phase.
To detect that the field stroke time is greater than the user-entered value, complete the following steps:

Procedure

  1. In the All Items tree, locate the damper percent command object.
  2. Right-click the object.
  3. Click Show Extensions. The Extension Wizard appears.
  4. Click New on the Alarm row.
  5. Click Other to select an attribute other than Present Value.
  6. Select Effective Stroke Time Inaccurate from the list of attributes.
    Figure 1. Select attribute

  7. Click Next. The Configuration dialog window appears.
    1. In the Name text box, type a name for the value.
    2. In the Normal State text box, set the value to False.
    3. In the Alarm Setup section, make the necessary adjustments according to your preference.
  8. Click Next. Set up of this alarm is now complete.
    Note: When the value of the Effective Stroke Time Inaccurate attribute turns to TRUE, it indicates that the actuator stroke time of travel is greater than the user entered value for the Effective Stroke Time. If this occurs, the Effective Stroke Time needs to be corrected in the controller program and re-downloaded for the alarm to clear.
